Reborn as a Snake, You Asked Me to Catch Criminals

[No cp + no heroine + system + solving crimes + vest + time travel] Since his sudden death after staying up all night, when Bai Yan opened his eyes again, he had changed into a different species - a big white spicy strip. Witnessing a murder at the beginning is not too exciting. As the only witness, Bai Yan said that his little heart couldn't bear it. Fortunately, the system arrived late at the critical moment. "Hello host, I am the anti-criminal system. Please call the police immediately." Bai Yan:? ? ? Comrade police, are you interested in cooperating? Later, the criminal police captain Zhang Cheng received a mysterious call. There was no phone number and no information about the caller could be found. Bai Yan: Team Zhang, I'm interested in your case. So the police force has a mysterious "non-staff member". Chasing the culprit relies on crawling, collecting evidence relies on drilling, and defending the culprit relies on sniffing. Zhang Cheng: Who are you? Bai Yan: Remember, my name is Bai Moxun. As a result, the name "Bai Moxun" became a legend. It is said that this person can always find evidence that they unexpectedly find. Zhang Cheng: ... I don't know why, but every time I arrive at a crime scene, I see a snake slithering around. (ー_ー)!! —————— Protect yourself from lightning, thank you lightly.
